fix: 修复新 UI 语言与文案显示问题 (#4876)

* chore(dev): add local setup state reset target

- add a reset-setup make target to clear setup records, root users, and related options.
- support both docker dev PostgreSQL and local SQLite development databases.
- restart the docker dev backend so setup status is recalculated after reset.

* fix(chat): prevent preset menu text overflow

- add truncation layout for chat preset names to keep long labels inside the sidebar menu.
- prevent loading and external-link icons from shrinking in constrained menu rows.

* fix(i18n): translate dashboard granularity options

- call t() for granularity option labels in dashboard system settings.
- keep localized text consistent between the select trigger and dropdown items.

* chore(dev): add backend dev service rebuild target

- add a dev-api-rebuild make target to rebuild and start the docker backend service.
- reuse DEV_COMPOSE_FILE and DEV_BACKEND_SERVICE variables to avoid repeated compose config literals.

* fix(i18n): align interface language option labels

- add shared interface language options to keep display names consistent.
- reuse the shared options in the header switcher and profile preferences.
- normalize language codes so zh-CN and zh_CN resolve to Simplified Chinese.

* fix(i18n): add missing frontend translation keys

- route channel key prompts, form validation messages, and channel fallback text through i18n.
- add missing translations across six locales for channels, rankings, billing, and logs.
- update i18n sync reports so literal t() keys are present in the base locale.
